目的应用超声手段探测儿童颈动脉内膜-中层厚度(IMT),探讨其与儿童肥胖类型的关系。方法依体质指数(BMI)、腰围身高比(WHtR)标准,入组外周性肥胖组160名(A组),内脏性肥胖150名(B组),正常体重儿童160名(正常对照组);应用超声手段探测各组儿童内脏脂肪厚度(VFT)和颈动脉内膜-中层厚度,比较3组间各项检测参数。结果内脏肥胖组VFT、IMT均高于外周性肥胖组及正常组,差异具有统计学意义(P<0.05);外周性肥胖组VFT、IMT与正常组相似,差异没有显著性。结论IMT与肥胖类型相关,内脏性肥胖儿童VFT、IMT增加。实时超声检查技术为研究儿童肥胖类型提供了一种新的检测手段。
Objective To detect the carotid intima - media thickness (IMT) in children with ultrasound and to explore its relationship with the type of childhood obesity. Methods According to body mass index (BMI) and waist circumference ratio (WHtR), 160 patients in group A (peripheral obesity), 150 in visceral obesity (group B) and 160 normal children (normal control group) were enrolled. Ultrasound was used to detect visceral fat thickness (VFT) and carotid artery intima-media thickness in each group. The detection parameters were compared between the three groups. Results VFT and IMT in visceral obesity group were higher than those in peripheral obesity group and normal group (P <0.05). VFT and IMT in peripheral obesity group were similar to those in normal group, but the difference was not significant. Conclusion IMT is associated with obesity type and VFT and IMT in visceral obesity children increased. Real-time ultrasonography provides a new means of testing for the study of childhood obesity.
